how wide is the deck? Is it 10 feet.

Good guess - 11'-0" from face of sliding doors

How deep is it?

The shelf is 6" deep, the remainder varies from 3.5' to 5.5'

Please do you have a design for a 20m by 5m wide bakyard for a pool? Thanks

How can I find out more about purchase and price for this magnificent pool?

I suggest finding a reputable local pool builder and discussing you project scope with them. There are multiple factors that they will bring up that will determine the price and permit requirements. Where will the pool be located?

What are dimmensions of the sun decking?

The main part of the deck that can be seen in the photo is approximately 11' x 38'.

What a beautiful design and workmanship. I was wondering if you could tell me the square footage of the entire area shown in this picture that shows the pool, deck and strip of landscaping. It looks like a rectangle of space but would love to see if I have the same square footage if I can fit this in my backyard.

Best pool design ever!!! I built mine based on this. Thank you!!!!

The space is approximately 60'x20', including - deck, pool and landscaping

Where can I get this deck? And what are the specifics for the exact item (color & model)?
